    "abstract": "We report on the spectroscopy of the $5s^2 {}^1S_0 (F=9/2) \\to 5s5p {}^3P_0\n(F=9/2)$ clock transition of ${}^{87}{\\rm Sr}$ atoms (natural linewidth of 1\nmHz) trapped in a one-dimensional optical lattice. Recoilless transitions with\na linewidth of 0.7 kHz as well as the vibrational structure of the lattice\npotential were observed. By investigating the wavelength dependence of the\ncarrier linewidth, we determined the magic wavelength, where the light shift in\nthe clock transition vanishes, to be $813.5\\pm0.9$ nm.",
